Summary

This trial is studying the safety and tolerability of an investigational combination of drugs, radium-223 plus pembrolizumab, for the treatment of castration-resistant prostate cancer.

Who is the study for?
Men over 18 with advanced prostate cancer that's resistant to hormone therapy can join. They must have had a biopsy confirming adenocarcinoma, show cancer progression, and have metastatic disease visible on bone scans. Participants need good organ function, an ECOG performance status of 0 or 1 (fully active or restricted in physically strenuous activity but ambulatory), and agree to use contraception.
What is being tested?
The trial is testing the combination of Radium-223 (a radioactive drug) with Pembrolizumab (an immunotherapy drug) for safety and effectiveness in treating castration-resistant prostate cancer that has spread to bones.
What are the potential side effects?
Possible side effects include fatigue, nausea, diarrhea, skin reactions at the injection site for pembrolizumab; radium-223 may cause nausea, diarrhea, vomiting and low blood cell counts which could lead to increased infection risk.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Radium-223Experimental Treatment1 Intervention
- Radium-223 will be administered intravenously every 4 weeks at a pre-determined dose
Group II: Pembrolizumab Plus Radium-223Experimental Treatment2 Interventions
* Radium-223 will be administered intravenously every 4 weeks at a pre-determined dose * Pembrolizumab will be administered intravenously every 3 weeks at a pre-determined dose Radium-223 will be halted after 3 doses. Once radiographic progressive disease occurs, the last 3 doses of radium will be given.
